William E. Bixby has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Photoconductor of varying light sensitivity from center to edges
    Patent number: 4210710
    Abstract: A member for electrostatographic reproduction formed of a substrate and having a photoconductive layer characterized by a sensitivity to light which is greater at the outer portions than at the center to compensate for fall-off at the extremes of radiation patterns.
    Type: Grant
    Filed: June 26, 1978
    Date of Patent: July 1, 1980
    Assignee: A. B. Dick Company
    Inventor: William E. Bixby
  • Photoconductors having improved sensitivity by presence of a like polar fields during imaging
    Patent number: 3958988
    Abstract: A method for developing a latent electrostatic image on a photoconductive surface which has previously been provided with an overall electrostatic charge of a predetermined polarity in which the charged surface is exposed to the image pattern of light and shadow for dissipation of the electrostatic charge in the light exposed areas while an electrode having an electrical potential of the same polarity as the electrostatic charge on the surface is positioned closely adjacent the charged surface.
